I was bad today

I had a slip up in training today. In week 2 of my training, my owner knows that I will try and see if they are ready to become the "Alpha" of our pack...that means I am going to test the waters. Needless to say, I did just that. I am currently being ignored by my mom. I nipped at her today. I was supposed to be sitting at the door like a good boy (before we go on our walk), waiting for my next command. Out of nowhere a big pit bull walks by our stoop. I got territorial (which I shouldn't be doing). Mom tried to correct my behavior and I almost nipped her. So today was not a good day. Hopefully tomorrow will be better.
